VSHELLINGND GRINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 298,260, dated May 6, 1884.

Application led January 31, 1884. (No model.)

To @ZZ whom it may concern:

Be it known that we, EDWARD M. WILcox, a citizen of the United States, residing at Vhitewater, county of Walworth, State of Wisconsin, and WILLIAM E. BorsroRD, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Shelling and Grinding Machines; and we do declare theefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or iigures of reference marked thereon, which form a part of this specication.

Figure 1 of the drawings is a rear View of our device, and Fig. 2 is an end view of the same.

This invention has relation to improvements in shelling and grinding machines; and it consists in the construction and novel arrangement of devices, as will be hereinafter more fully set forth and claimed.

Heretofore it has been the general custom to perform the operations of shelling and grinding separately, requiring a loss of time and expense. It has been necessary to pass the corn through the sheller by one operation, and then to pass 4it through the grinder by another operation; and very few, ifl any, machines have been devised, in the knowledge of these applicants for Letters Patent, which would reduce the operation to one of simplicity, requiring no more`power to perform both the shelling and the grinding, and requiring less help to tend the operation of the combined machine. The particular kind of a grinding-machine, to which this combination of the shelling attachment is applicalole in our invention, is generally known as a sweep-power iron grinding-mill. The power is applied by a team attached to the end of a sweep, generally about twelve feet long. The team moves in a circle, as on a horsepower of a thrashing-machine. We place at the extreme end of the sweep K a wheel like a common mower-wheel, which has a spurgear, B, attached thereto,.and revolves with 5o the wheel A upon -a common axle, which is securely bolted to the under side of the sweep at its Vextreme end. O11 top of the sweep K, secured in place by proper boxings, we place a shaft, D, parallel with the line of the sweep,

and at the end which is in proximity with rthe largewheel and spur-gear we place a spur-pinion, E, upon said shaft,'which we engage in mesh with the cogs of the spurgear. Upon the inner end of this shaft, or end next to the grinding-mill, we place a pulley, F, of proper diameter and face to give the requiredspeed to the corn-sheller. Making a platform upon the upper side of the sweep directly around the grinding-wheel, we place upon said platform a common cornsheller, which is supplied with a pulley, G,

to operate it by. We then belt from the pulley upon the shaft D to the pulley onY the corn-sheller, and the machine is ready for operation. The weight of the wheel at the outer end of the sweep gives it a sufficient engagement with the ground, so that it gives motion, by revolution on its axle, to the spurpinion engaged with it, which is secured to the shaft, and motion is likewise imparted to the pulleys, belt, and corn-Sheller. The earcorn being fed into the corn-Sheller is rapidly shelled, and the shelled corn drops directly into the hopper of the grinding-mill H, and is 'in turn ground into meal. By placing a basket upon the platform in such position as to catch the cobs which drop from the sheller, said cobs are not allowed to be in the way of working to advantage. With a wheel at the end of the sweep, which has a diameter of thirty inches, we have so geared and pulleyed the machines that we get three hundred revolutions of the corn-Sheller for every four revolutions ofthe sweep, which generally consumes one minute of time, and is considered to be the proper speed.

Having thus fully described our invention, we desire to claim and to secure by Letters Patent The combination, with agrinding and shell in` machine7 of the Sweep l, having the drive- In testimony whereof We affix onil signatures wheel A, provided with a spur-gear, B, and the in presence of two Witnesses.

shaft D, journaled upon said sweep, provided vf ,Y v r :Lt its outer end with :i pinion to mesh with the spur-gear, and at its inner end'with apulley to operate a heit connecting` with the pul- XViinesseS:
